When I have a gate or an output pin in a sub circuit and there comes an active wire from other logic to the output of that gate or an output port of a sub circuit, there is an error which says 'Contention Error, 1 and 0 at AndGate in Main'. It prevents me from building a bus with several registers as no of the outputs can be connected to each other. As a fix I would recommend a diode 'Gate', which only lets current flow in one direction, or just the removal of that error message. In reality nothing happens when you apply voltage to the output of a logic gate, but in this simulation it stops and won't simulate any further.

If you want to create a bus you should use a Splitter (look for it in the Misc section). If what you are trying to do is to join several outputs together then you may try using 3-state buffers.

Im trying to do the same thing, I've been fricking doing the same stuff for hours, I'm just trying to get a output of my keys (0-9 buttons) to lock in place once i press them so if i press 8 i will get 1000 and that is stored in a 4 bit ram and i can use that latter, but nooooo i cant do anything i try, and no splitters don't work
